source code doesn't compile

I downloaded the dovecot source and it doesn't compile. The install script fails in auth because it makes a file and then tries to make a directory over it make[2]: Entering directory '/home/ruben/src/dovecot-2.3.17.1/src/auth' make[3]: Entering directory '/home/ruben/src/dovecot-2.3.17.1/src/auth' /usr/bin/mkdir -p '/usr/local/lib/dovecot' /bin/sh ../../libtool --mode=install /usr/bin/install -c auth checkpassword-reply '/usr/local/lib/dovecot' libtool: warning: 'libstats_auth.la' has not been installed in '/usr/local/lib/dovecot/old-stats' libtool: install: /usr/bin/install -c .libs/auth /usr/local/lib/dovecot/auth libtool: install: /usr/bin/install -c .libs/checkpassword-reply /usr/local/lib/dovecot/checkpassword-reply /usr/bin/mkdir -p '/usr/local/lib/dovecot/auth' I am running an older version of dovecott and would really like to upgrade it and there is no package for this linux version -- So many immigrant groups have swept through our town that Brooklyn, like Atlantis, reaches mythological proportions in the mind of the world - RI Safir 1998 http://www.mrbrklyn.com DRM is THEFT - We are the STAKEHOLDERS - RI Safir 2002 http://www.nylxs.com - Leadership Development in Free Software http://www2.mrbrklyn.com/resources - Unpublished Archive http://www.coinhangout.com - coins! http://www.brooklyn-living.com Being so tracked is for FARM ANIMALS and extermination camps, but incompatible with living as a free human being. -RI Safir 2013

Migrate mail_location
by hello＠reox.at 11 Jan '22

11 Jan '22

Hi! I have a dovecot installation, with the following configuration: mail_home = /var/vmail/%d/%n mail_location = maildir:~ I would like to migrate the mail_location to maildir:~/mail, to get around the issues described in the documentation. But I can not really find a good way to do that. I played around with doveadm sync/backup, but I can only copy everything into a new location (i.e. doveadm sync maildir:~/mail), but this does not really untangle the mail_home and location. My other idea was to migrate the maildir manually, i.e. move the maildir related folders and files (new, cur, tmp, all folders starting with a dot and containing itself {new,cur,tmp}, dovecot.* files, subscriptions file) into the ~/mail folder, but I'm not sure if this is a safe method. Is there any safe method to do this using dovecot tools? If the only way is a offline migration, I'm fine with that. Best, Sebastian

Hi, my dovecot 2.17.1 instance is crashing a lot. Quick question: The coredump should contain some private data, am I correct ? Assuming so, should it be posted on a public maillist? Panic: file dsync-ibc.c: line 166 (dsync_ibc_send_mail_request): assertion failed: (request->guid != NULL || request->uid != 0) ...

Spamassassin fails
by Hans Brage 10 Jan '22

10 Jan '22

Hi! I've been running a server with Dovecot, Sieve, Spamassassin and getmail to handle my emails for several years now. Just before christmas I did one of these regular updates and since then I got problems with spamassassin. Quite a lot of spam is not been filtered out. I can see a lot of errors like these in the mail-log. spamd: failed to create readable default_prefs: /home/vmail/.spamassassin/user_prefs Vmail is the user that is running my scripts that retrieves email and executes spamc. Any ideas? Regards, Hans

outlook 2019 not working

10 Jan '22

Just tried connecting a Windows 10 client with Outlook 2019 but it fail's on both POP3 or IMAP - i knew it was working when i tested it after the server setup about a year ago because i documented everything with screenshots. All other devices we use (Thunderbird, iPhone/iPad, Android devices, RoundCube) are working without any issue, just Outlook won't connect anymore. We don't have much Windows/Outlook experience - any help/hints appreciated.

Patch: assertion failed in doveadm fts lookup
by John Fawcett 09 Jan '22

09 Jan '22

Hi I'm reposting this patch, which I have been applying locally since I originally posted it. Hopefully it can be considered for inclusion in the official release. It was tested on dovecot 2.3.16 but applies against the latest version 2.3.17.1.

Non-user logins?
by Ken Wright 09 Jan '22

09 Jan '22

My Dovecot issues continue. Right now I see at least two issues: first, my logs consistently show non-users trying (and failing) to log in, and I'm still unable to log in from my email client (Evolution or Roundcube, either one). I'll post about the second issue later; right now I wonder why I'm getting so many non-users trying to log in. Am I the subject of concerted hacking attacks, or is there something else going on? Some of the attempted logins are more-or-less random names claiming to be @mydomain, but at least one is a username that's really on my server, to wit: Jan 7 22:52:01 grace dovecot: lmtp(776281): Error: lmtp-server: conn unix:pid=776262,uid=117 [3]: rcpt www-data(a)mydomain.com: Failed to lookup user www-data(a)mydomain.com: Internal error occurred. Refer to server log for more information. (Another quick question: which server log should I check?) So, if anyone can tell me what's going on with all these logins, I'd be much obliged! Ken

Patch: enhancements for solr/tika integration
by John Fawcett 09 Jan '22

09 Jan '22

Hi here's a patch with some enhancements that I am applying locally for solr/tika integration. Hopefully this can be considered for inclusion. I've tested up to 2.3.16 and this patch applies against latest version 2.3.17.1. The contents are: 1. Allow username and password in tika configuration (as is already supported for solr). For example: fts_tika = https://user:password@tika_host:tika_port/tika/tika This means that tika can be more easily located on a different server to dovecot. Locating Solr and Tika on separate servers can isolate the Dovecot server from issues that may happen on Solr or Tika (like out of memory). 2. Introduce an optional configurable limit on the size of emails whose message bodies will be indexed with solr via a new setting fts_max_size, to be put in the plugin section. For example plugin { ... fts_max_size = 2M ... } Message body indexing is skipped for messages that are larger than this setting. 3. Introduce an optional configurable limit on the size of emails whose attachments will be sent to tika for keyword extraction, via a new setting fts_max_size_tika, to be put in the plugin section. For example: plugin { ... fts_max_size_tika = 1M } I noticed that some very large attachments are being sent to tika and these often do not have any useful content to index. For simplicity the check is done on message size not individual or total attachment size.

Patch: safeguard against too large value for uid being sent to solr for single mailbox searches
by John Fawcett 09 Jan '22

09 Jan '22

Hi I'm reposting a patch for solr integration which I have been applying locally. It applies against 2.3.17.1. Dovecot already has a mechanism when doing solr fts searches on multiple mailboxes that prevents a too large value for maximum rows being sent to solr. #define SOLR_MAX_MULTI_ROWS 100000 (defined and used in plugins/fts-solr/fts-backend-solr.c) However on single mailbox searches Dovecot uses the last uid of the mailbox, which can be too large for solr. My suggested patch is to also limit maximum rows to return on single mailbox searches. Here is the patch: diff -ur dovecot-2.3.17.1-orig/src/plugins/fts-solr/fts-backend-solr.c dovecot-2.3.17.1-new/src/plugins/fts-solr/fts-backend-solr.c --- dovecot-2.3.17.1-orig/src/plugins/fts-solr/fts-backend-solr.c 2021-12-03 12:48:47.000000000 +0100 +++ dovecot-2.3.17.1-new/src/plugins/fts-solr/fts-backend-solr.c 2022-01-09 01:33:23.401341959 +0100 @@ -837,7 +837,7 @@ str = t_str_new(256); str_printfa(str, "wt=xml&fl=uid,score&rows=%u&sort=uid+asc&q=%%7b!lucene+q.op%%3dAND%%7d", - status.uidnext); + I_MIN(status.uidnext,SOLR_MAX_MULTI_ROWS)); prefix_len = str_len(str); if (solr_add_definite_query_args(str, args, and_args)) { John
